Background Information
TSG101(Tumor susceptibility gene 101 protein) is essential for endosomal sorting, membrane receptor degradation and the final stages of cytokinesis. It plays a crucial role for cell proliferation and cell survival. TSG101 has been identified as a candidate tumor suppressor gene and belongs to the ubiquitin-conjugating enzyme family. TSG101 is a marker for exosome. This protein has 2 isoforms produced by alternative splicing with the molecular mass of 44 and 32 kDa.

Reviews
What customers say
All five reviews rated the antibody 5 stars. Users report consistent success in Western Blot and Immunofluorescence, with dilutions ranging from 1:1000 to 1:10000. Tested samples include mouse liver tissue, cancer cells, cancer cell-derived exosomes, and trophoblast-derived exosomes. One user confirmed TSG101 bands at the expected 42 kDa in mouse liver lysates. Multiple reviewers described the antibody as working well and highly recommended it, with one user noting they had ordered it three times for reliable results.
